Masayoshi Saito: Syaoran-kun is the same. A strong kudan, the best kudan, only goes with people who have a strong mind. A kudan is something that is controlled by the mind. A kudan reflects a person's strength of mind and I admire that.

Syaoran: The princess... smiled at me. I told her I didn't remember anything from the past. She wasn't angry at me, and she wasn't pitying me. She even decided a birthday for me. It's today, April 1st. And then she smiled at me. The princess's smile... It's so warm.
